Wallace, 38, hasn't played in the NBA since the 2009-10 season. But multiple sources said Wallace worked out at the Knicks' practice facility last week and is considering a return to the NBA. He has a good relationship with Knicks coach Mike Woodson, who was an assistant with Detroit when Wallace helped the Pistons win the 2004 NBA championship.

The Knicks are looking for a defensive-minded backup power forward/center. Wallace can be volatile, but he would seem to be a low-risk, high-reward option for the veteran team, which is looking to advance past the first round of the playoffs for the first time since the 1999-2000 season.

The 6-10 Wallace has averaged 14.6 points over 15 seasons and was one of the better low-post defenders during his career. The four-time All-Star played in 177 postseason games, and appeared in three NBA Finals.
